Abstract:
The incidence of colorectal cancer (CRC) is increasing year by year, and early diagnosis is of great significance to improve the prognosis of patients. Circulating cell-free nucleic acid (cfNA) has the advantages of non-invasive, real-time monitoring, and overcoming tumor heterogeneity. The characteristics of cfNA content, mutation, methylation and fragmentation patterns provid important reference value for early diagnosis, curative effect monitoring, prognosis judgment and medication guidance of CRC. However, the practical application of cfNA in the clinical diagnosis and treatment of CRC still needs to solve the problems of unstandardized detection technology, high detection cost, screening of markers with high diagnostic efficacy, and construction of multi-combination models. These challenges will provide new directions for future cfNA research.
